We did the Muir Wood and Sausalito in the morning til 1:00 with Best Bay. We did Alcatraz on our own, buying tickets for the 2:10 time slot. Enjoyed all we did very much!
If you really want to ride the Cable Car, you need a plan. You need to get a taxi and drive to the CA line. Otherwise, you will spend half your day in line trying to get a ticket then getting in line to actually ride. We tried and gave up, getting the taxi and going to the other line.
